Which blast media?

not a fan of any slag (copper or coal) too dirty and has trace arsenic in it from the refining process. it also has water issues (nobody has ever had their black sand pot plug up have they? lol) sand is a no-no too.
I use glass on almost all of my stuff. grit depending on how rusty it is. I am not really a industrial blaster. we do more specialty stuff than just gravel boxes and truck frames. houses, fire damage, higher end cars, airplane stuff ect

im not afraid to use new medias and when I first started I bought every product in every grit I could get. all have their advantages and disadvantages

you will ask 10 blasters and get 15 different opinions on the best media. most industrial guys blast whats cheap to maximize profit. (black beauty) I blast what is best and worry about profit later. that's why I have customers from 500 miles away bringing me projects knowing they passed 10 blasters to get to me. I currently blast soda, walnut, glass (20-50, 30-60, 50-100, 100-200 and 250 grit) Garnet (red, green and black) alox, as well as a custom mix we have been making for wood products (furniture)

on the rusty scale chris, I would probably go a 30-60 maybe and quickly reblast with a 100-200 after to break the sharp edges down.
